The space allocated to each person in the train or bus is not very big,but luggage rack is provided in both places, thus the luggage casesystem is designed as detachable, the luggage case can be detached andplaced on the luggage rack, the base or frame doesn't occupy lots ofspace. This system is divided into luggage 74 and base (or frame) 77 (inFIG. 18). Luggage case 74 is locked to the base 77 in the way ofhit-then-lock, certainly it can locked to the base via lock, magnet andhook and loop.

It can seen in FIGS. 25-30 that there are three guide rods 51 and twohooks 52 in the bottom of luggage case 55 (or 74); there is a slantmatching the slant of the horizontally sliding block 57, neck and hookhead in hook 52; there is a spring pin room in the middle of the bottomof frame 54 (or 77), there is an horizontally sliding block 57 with aslant, several, springs 58, a vertically sliding block 56 with a slantand a cover 53 to keep all the parts in the room in the spring pin room;there are also several small holes 69 through which the hook 52 of thebottom of the container moves; there is a hole 60 through which thevertically sliding block 56 moves; there are several guide holes inframe 54 (or 77), the guide rod 51 of the container can move throughthese guide holes; the slant of the vertically sliding block 56 matchesthe one of the horizontally sliding block 57; there are two holes in therear of the horizontally sliding block 57, part of the spring 58 is inthe hole thus the spring will not jump out; when the user places thecontainer 55 on the frame 54, the guide rods 51 enter the guide holes ofthe frame 54 (or base) due to the gravity, and at the same time thegravity of the luggage case pushes hook 52 to push the horizontallysliding block 57 into the rear of the spring pin room, the spring 58 iscompressed; when the hook 52 enters at some depth, its neck widthbecomes narrow, the horizontally sliding block 57 is pushed frontwardsby spring 58 behind it and then lock the hook 52, thus the luggage case55 is locked to the frame 54.

When the user wants to lift the container out of the frame, use a footto step the vertically sliding block 56, the block will slide downwardsalong the hole 60 to push the horizontally sliding block 57 to the rearof the spring pin room, then the horizontally sliding block 57 leavesthe hook of the container, which unlocks the luggage case, then theluggage case 55 can be lifted out of the frame.

2) There is a concave shape with top open to hold human face in theheadrest. Referring to FIGS. 18 and 47-51: there is a hole to hold humanface in headrest 86. If the headrest is flat and the head is placed onit hen the neck is twisted too much and makes user uncomfortable; ifthere is a concave shape with top open, then neck can be placedcomfortably in the concave shape and rest on it comfortably withoutbeing twisted.

Headrest 86 is fastened on the handle, the middle of the handle is alittle bit lower than the edge because hands need to grasp the handle,pull the handle or lift the luggage case. There is other embodiment forheadrest. For example, 71 of FIG. 47, a gap in the middle rear; forexample, headrest in the middle of which there is a concave shape withadjustable width in FIGS. 48-51.

There are two cushions in the headrest, one cushion 120 can be moved,the other cushion 121 is fastened on base 122 and is still; these twocushions form a concave shape 119 with bottom and two gaps; the width ofthe concave shape can be changed by changing the position of 120, thusthe concave can match different face shape; the two long edges of theconcave shape can be straight lines, can be convex arc to match thecontour of head and face more perfectly.

Cushion 120 is fixed on groove 133, and there is a square rod 132 in thebottom of the groove 133; there is a hole 123 in the headrest base 122;there is a protrusion 130 with teeth on one side of the hole 123; thegroove 133 and the cushion 120 can be moved by sliding square rod 132 inhole 123; the square rod 132 is enclosed with spring 125, sliding block126 with teeth and handle 127 one by one after the rod 132 goes throughthe hole 123. There is a hole in the middle of sliding block 126; thespring 125 presses the base 122, sliding block 126 presses spring 125,handle 127 presses sliding block 126 with teeth. The axle 131 goesthrough the axle holes of the handle 127 and the square rod 132 andfasten the handle on the square rod; the handle 127 can rotate on theaxle 131; when handle 127 rotates the distances between the edges ofinterface of the handle and sliding block 126 and axle 131 aredifferent; as can be seen in the FIG. 49, handle 127 presses spring 125down, the sliding block 126 with teeth goes down, its teeth match theteeth on the protrusion 130, sliding block 126 cannot move because it islocked by teeth; rotating the handle to the other side drives the axleof the handle 127 closer and closer to the contacting edge with slidingblock 126, spring 125 pushes sliding block 126 upwards, thus the teethof sliding block 126 is out of touch of the teeth of protrusion 130because of moving up, then moving handle 127 can move cushion 120;rotating the handle to the other side again drives the axle of thehandle 127 further and further from the contacting edge with slidingblock 126, handle 127 presses sliding block 126 down, spring 125 iscompressed, the teeth of sliding block 126 match the teeth on theprotrusion 130, sliding block 126 cannot move because locked by teeth.The edges of the teeth of protrusion 130 and sliding block 126 beingcontacted are rounded, thus the teeth of the sliding block 126 can enterteeth of protrusion 130 easily when sliding block 126 is pressed down.The headrest with concave shape with adjustable width can be fixed onthe pull rod. One of the advantages of this kind of headrest is that thewidth adjusting parts cannot be uninstalled or lost.

3) The angle of the chest support frame and the ground can be adjustedwithout inserting pin using hand.

Referring to FIGS. 18-24, chest support frame 84 is divided into upperand lower support frame, there is a lever like button (FIG. 4) to adjustthe length of the two support frames, referring to claims 7 and 8. Thelower chest support frame and two frame accessory ears 85 are connectedto pin 95 and 100 via axle 89. There are one axle hole and several pinholes in the ears, inserting pins 95 and 100 into different pin holes 88of ears can adjust the angle of ground and connection part of chest restor change the support frame to be in use or folded status; axle 89 goesthrough the axle holes of ears and axle hole 93 of the lower chestsupport frame 842. The lower chest support frame 842 can rotate betweenthe two ears 85.

There is a spring pin room 103 in the lower end of the lower chestsupport frame 842, there is a pin in left 100 and right 95 siderespectively in the room, the pins are enclosed by compression spring 99and 100 respectively; there is a lever 91, one end is verticallyrotating block 97, the other end is button, axle 94 goes through themiddle of the lever, there is compression spring 92 under the button;and there is support frame 98 and cover 90 in the room. The lowerextension walls of support frame 98 and cover 90 form support wall witha hexagon hole to support tails 102 and 96 of left and right pin andlimit the movements of the tails in the hole. The pin are enclosed withcompression spring but the tail is bigger than spring, thus the springcan push the pin tail to move in the hexagon hole.

The pin tail is bigger than the pin head, and there is a slant in thepin tail, there is a vertically moving block 97 in the middle of the twopin tails, there are two slants matching the slants of the pin tail onthe both sides of the moving block 97, the distance between two sides ofthe sliding block become smaller gradually along the slants.

There is a cover 90 with a hole in spring pin room 103, there is abutton 91 in the hole, pressing button 91 can drive both side pins 95and 100 move horizontally; when the vertically moving block 97 is stableits widest part is clamped between the tails 102 and 96 of two pins, thesprings 101 and 99 on the pin 100 and 95 are compressed, pins 100 and 95are driven out of the chest support frame 84 and enter the pin holes 88of the ears, thus the chest support frame 84 is fixed and cannot berotated on the axle 89; when the button 91 is pressed, the spring 92under the button is compressed, the button drives the vertically movingblock 97 move upwards, and the part clamped between the two pin tails102 and 96 will become narrow, the spring on the pins will expand topush the pins 95 and 100 inwards and out of the pin holes 88 of theears, thus the chest support frame 84 can rotate on the axle 89; whenthe chest support frame is rotated to a proper place, release the button91, the compression spring 92 under the button will expand and push thebutton upwards to drive the vertically moving block 97 to be lower,enter the middle of the 2 pin tails 102 and 96, because the enteringpart becomes wider and wider, push pins 95 and 100 to out of the holesof the lower chest support frame, and pins enter the axle holes 88 ofear 85, thus the chest support frame 84 is fixed.

The button 91 is connected with vertically moving block 97 like a lever,there is a axle hole in the connection, an axle 94 is in the hole andthe button 91 and moving block 97 is on the two sides of the axle 94respectively; when the button is pressed, the spring under it iscompressed, the vertically moving block rotate upwards, the part clampedbetween two pins becomes narrow; when the button is released, the springunder it expands to rotate the vertically moving block downwards, thepart clamped between the two pins become wide.

The two lower extension wall in the rear of the cover 90 can preventlever button from moving left or right; the middle of the bottom ofsupport frame 98 is comparatively thick prevents vertically moving block97 from moving downwards further.

The advantage of the this structure is to change the angle of the groundand chest support frame 84 without using hands to insert pins, pins arepart of the chest support frame and never loss thus it is a verygraceful design.

4) there is a pedal behind the frame, the vertical rotation of the pedalcan be changed to horizontal rotation by two tapered gears, and drivesthe front foot to be rotated out by horizontally rotating gears (seeFIGS. 31-37). There is a pedal 652 which sticks out horizontally fromupper part of pedal 65 for foot to step, and one gap 651 hooked bytorsion spring 67 in the bottom of pedal; there is an axle 72 in theaxle hole in the bottom of pedal 65, a torsion spring 67 encloses theaxle 72; there is a spring pin room in the base 68 beside pedal, thereis a spring 71, an horizontally sliding block 69, a vertically slidingblock 70 and a cover to keep all the parts mentioned above in the roomin the spring pin room.

Axle 72 goes through the axle hole 681 in the luggage case frame orbase, one locknut 73, pedal 65 and torsion spring 67, then is fastenedwith the vertically rotating tapered gear 64, axle is fastened withpedal 65, the rotation of pedal 65 will drive gear 64 to rotate. Thereis horizontally rotating gear 62, foot 61 with gear 611, tapered gear 63with horizontally rotating transmission gear 631 in base 68, taperedgear 632 engages gear 64, transmission gear 631 engages rotating gear62, rotating gear 62 engages gear 611; gear 631 and gear 632 shares thesame axle and rotate at the same time, gear 611 and foot block 612 sharethe same axle and rotate at the same time. Pin 69 and sliding block 70both has a slant, and both slants match with each other; the movement ofpin 69 will drive sliding block 70 to move, and vice versa.

When the user sleeps on this system, first steps down pedal 65 anddrives axle 72 to rotate down, torsion spring 67 is twisted further,axle 72 drives gear 64 to rotate clockwise, gear 64 drives gear 632 andgear 631 rotate anti-clockwise, gear 631 drives gear 62 rotateclockwise, gear 62 drives gear 611 and foot block 612 rotateanti-clockwise or forward to out of the bottom; when pedal 65 is laidhorizontally, horizontally sliding block 69 is pushed forwards by spring71, and finally locks the hilt of pedal 65, thus gears above, torsionspring, foot and pedal are all fixed and cannot move, vertically slidingblock 70 goes up. The foot is rotated out of bottom and prevents thesystem from falling forwards.

When user doesn't want to sleep on the system, uses foot to step downthe vertically sliding block 70, sliding block 70 drives the slidingblock 69 to move back to hole, when sliding block 69 leaves the neck ofthe pedal, torsion spring 67 is reset to drive pedal 65 to rotateupwards, drives axle 72 rotate upwards, axle 72 then drives gear 64rotate anti-clockwise, gear 64 drives gear 632 and 631 to rotateclockwise, gear 631 drives gear 62 to rotate anti-clockwise, gear 62drives gear 611 and foot block 612 to rotate clockwise or back to thebottom. At the same time some part of pedal 65 stays in the gap 682 ofthe base, thus prevents block 69 from sticking out of the spring pinroom.

The advantage of this structure is that user just need to move his footto rotate the front foot on the bottom out and back to bottom withoutbending down, foot can be fixed even after rotating out.

5) There is another embodiment to rotate the front foot out: there is apedal behind the frame or base, the vertical rotation of the pedal istransmitted by transmission rod, thus drive the front foot forward andout (See FIGS. 18, and 38-40).

This section and the 4th section share lots of parts such as pedal,torsion spring and all the parts in the spring pin room.

There is a board sticking out horizontally for foot to step in the upperof pedal 75, a gap 751 in the bottom of pedal, the gap is over thetransmission rod 80; transmission rod 80 is a bent rod, one part is likestaple, and one end is bent to be perpendicular to other part, the bentpart goes through the gap 751 of the pedal 75; the other end of thetransmission rod is inserted into the hole of the front foot 76; foot 76can rotate on axle 82; there is an axle hole in the bottom of pedal 75,there is an axle like axle 72 in FIG. 34 in the axle hole, the axle goesthrough torsion spring 79; there is a spring pin room beside pedal inthe base 77, there is a horizontally sliding pin 81 whose end goesthrough spring 83, and vertically sliding pin 78 and a hidden cover(similar to cover 66 in FIGS. 34 and 35) keeping all the parts in theroom in the spring pin room.

Axle (Referring to axle 72 in FIG. 34) goes through one axle hole(hidden and referring to 681 in FIG. 34) in the luggage case frame orbase 77, a locknut (hidden and referring to locknut 73 in FIG. 34),pedal 75 and torsion spring 79. Axle and pedal 75 are fastened together,the rotation of pedal 75 drives transmission rod 80. Transmission rodgoes through the hole in the base, thus it can not move left, right orvertically, can only move frontwards and backwards; transmission rod isinserted into the big hole of foot 76, its frontwards or backwards movecan be changed to the rotation of foot 76.

Pin 78 and sliding block 81 both have a slant which matches with eachother; the movement of pin 78 will drive sliding block 81 to move, andvice versa. When the user sleeps on this system, first steps down pedal75 and drives 75 to rotate down on axle, torsion spring 79 is twistedfurther, gap 751 of pedal 75 pushes transmission rod 80 forwards,transmission rod push foot 76 forwards or rotate foot 76 out of thebottom. When pedal 75 is laid horizontally, horizontally sliding block78 is pushed forwards by spring 83, and finally locks the hilt of pedal75, thus transmission rod, torsion spring, foot and pedal are all fixedand cannot move, or movable range is very little and won't affect theuse, vertically sliding block 78 goes up. The foot is rotated out ofbottom and prevents the system from falling forwards.

When user does not want to sleep on the system, uses foot to step downthe vertically sliding block 78, sliding block 78 drives the slidingblock 81 to move back to hole, when sliding block 81 leaves the neck ofthe pedal 75, torsion spring 79 is reset to drive pedal 75 to rotateupwards, the gap 751 of pedal 75 pulls the transmission rod 80 back,transmission rod 80 pulls foot 76 or rotates foot 76 back to the bottomof the base. At the same time some part of pedal 65 stays in the gap 771of the base, thus prevents block 69 from sticking out of the spring pinroom. The advantage of this structure is that user just need to move hisfoot to rotate the front foot on the bottom out and back to bottomwithout bending down, foot can be fixed even after rotating out. It ispossible that there is no torsion spring because the foot can be used topush up the pedal to reset.

In order to prevent the system from falling forwards, an automaticallyfoldable pedal is added to the side of the base (See FIG. 41), to use afoot to step on the pedal can achieve this aim. The automaticallyfoldable pedal is composed of a rotatable pedal 108, spring 106, rod 105and 107. The spring 106 hooks rod 105 and 107. When the user want to useit, the user steps down 108, the spring is elongated; when the userdoesn't want to use, lifts the foot, the spring pull 108 back. Certainlyautomatic folding can be implemented with torsion spring.

6) There is another embodiment to rotate the front foot out: there is apedal which can be folded by rotation, stepping on the pedal to drivesthe front foot to rotate out via gears. Referring to FIGS. 42-46, spring116 hooks the side 1121 of frame 112, the other end of spring 116 hookspedal 109, the other end of 119 is over axle 117, axle 117 goes througha wall of frame 112, and is enclosed and fastened with a verticallyrotating tapered gear 110 on the other side of the wall; the rotation of109 rotates axle 117 and rotates tapered gear 110 too. Tapered gear 110engages a horizontally rotating tapered gear 111, tapered gear 111 andtransmission gear 1111 share the same axle 1112; transmission gear 1111engages one of the gears 113, there are 2 engaging transmission gears in113, the other one engages transmission gear 1142, transmission gear1142 and foot 1141 share the same axle.

When pedal 109 is stepped down, spring 116 is stretched, axle 117rotates and rotates 1141 forwards and out via gears 110,111,1111,113 and1142; when the foot lifts, spring 116 restores and pulls pedal 109 back,axle 117 rotates, rotates foot 1141 back via gears110,111,1111,113,1142. We can change extension spring 116 to torsionspring to do the same thing.

Using a big cover to cover all the parts in the base and leave space forstoring stuff, we can store stuff on the cover. The advantage of thisstructure is that stepping on the pedal not only rotates the foot out,but also prevents the system in use from falling forwards (when somebodyis sleeping on this).

When we want pedal 109 not to rotate upwards after being stepped to thebottom (that is to say, pedal doesn't rotate after the foot leaves thepedal 109), we can add a spring pin room to lock pedal 109 like thesection (4) or (5), or use magnet attraction.

The details are as follows, referring to FIG. 55 side pedal 109 isreplaced with a side pedal 143 with magnet, the end without magnet 1431is bent upwards, magnet 1433 is embedded in the side panel 1432, thereis a magnet embedded in the lower of the side panel 1121 of frame 112,when the pedal is stepped down, that magnet corresponds to magnet 1433,two magnet attract each other to prevent pedal 143 from rotatingupwards; when user would like to fold pedal 143, uses a foot to push theupwards bent end 1431 of the pedal to overcome the magnet attraction topush 143 to folded position, at the same time axle 117 rotates to rotatefoot 1141 back via gears 110,111,1111,113 and 1142. There is a sideprotrusion 1434 from pedal 143, the foot can step the pedal in a betterway with the protrusion 1434.

7) There is another embodiment to rotate the foot frontwards: there is avertically moving pedal on the side or rear of the base, stepping pedalcan drive the front foot to rotate out via rack of the pedal and othergears.

Referring to FIGS. 56-59, there are lots of vertically aligned teeth onpedal 144 and a side protrusion 1141 with slant; teeth of pedal engagetapered gear 64 or its accessory gear; a compress spring 147 is placedunder pedal 144. There is a spring pin room beside the pedal 144; thereis an horizontally sliding block 145 with two slants, a verticallysliding block 70 with a slant, a compression spring 71 behind verticallysliding block 70, and a cover 66 with a hole to keep spring and twosliding blocks in the room in the spring pin room; the slants of twosliding blocks 145 and 70 match mutually; the slant of pedal 144 and theother slant of horizontally sliding block 145 matches mutually; there isa ring 1461 in the base 146, the hilt of pedal 144 moves vertically inthe bole of ring 1461; when the pedal 144 is stepped down, the spring147 under it is compressed, the horizontally sliding block 145 in thespring pin room is pushed into the room further, the spring 71 behind itis compressed, and lifts the vertically sliding block 70 via slant, butwhen the pedal is stepped down to certain depth, the pedal head incontact with the horizontally sliding block 145 suddenly become small toits neck, the horizontally sliding block is pushed out by the spring 71behind it to lock the pedal 144; in addition, the gear on the pedal 144drives the tapered gear 64 to rotate downwards to rotate the foot 611out of the bottom via tapered gear and other gears. Refers to section 4for how the movement is transmitted to foot with gear via tapered gears,their mechanism is the same.

When the vertically sliding block 70 is stepped down, the horizontallysliding block 145 is pushed towards the spring pin room and leave thehilt of the pedal 144 via slant, the spring 71 behind the horizontallysliding block is compressed; there is no more obstacle on the top of thepedal 144 hilt, the spring 147 under the pedal handle expands, drivespedal 144 to move upwards, the gear on the pedal drives the tapered gear64 to rotate, which will drive the front foot 611 to rotate back to thebottom via tapered gear 632 and other gears. Refers to section (4) forhow the movement is transmitted to foot with gear via tapered gears,their mechanism is the same. It is possible that there is no spring 147under pedal 144 because its horizontal protrusion can be pushed upwardsby foot, which does the same thing as the restoration of the spring. Theadvantage of this structure is that the pedal doesn't need to rotatebackwards, thus the system occupies less space, and user cannot see thepedal, which means the exterior looks more beautiful.

The present invention and its implementation are described as above,this description doesn't have any limit, what are shown in the figuresis just one of the implementations of present invention, the realstructures don't limit to what are shown here. Thus if technicians ofour field is inspired by present invention and under the situationswhich is still covered by present invention, all non-creative designusing other format or similar structure and implementation case topresent design, are inside the protection scope of this patent,
